armar (first-person singular present armo, first-person singular preterite armei, past participle armado)[1]
Etymology
It is inherited from Latin armō (“to arm, equip”), written Old Galician-Portuguese armar in the oldest texts.[2][3][4][1] Machado gives the Latin verb the senses “arm”, “fit out a ship”, “arm a fortress” and “provide”, all of which reappear in Portuguese.[4]
The same Latin verb is Galician armar, Spanish armar, Catalan armar, French armer, Italian armare and Romanian arma.[5][6][1]
The Latin verb is formed from arma (“arms, weapons”).[7][1] Medieval Latin also used it for knighting someone by handing him his arms, a sense found in Old Galician-Portuguese too.[8][9]
Earliest recorded meaning
Houaiss and Cunha date the verb to the 13th century.[2][3] Machado's first record is a cantiga of Afonso X about a man who fled the war in fear and went back to his land armar manto, literally “to put on a cloak”; the glossaries read it as dressing up richly, perhaps to cover his cowardice, and mark the reading as uncertain.[4][10][9] The Cantigas de Santa Maria have a sultan who has his men armed, and crossbows made ready (ouv'a baesta armada “he had the crossbow cocked”); a cantiga d'amigo speaks of the king fitting out a boat (U el-rei arma o barco).[9][10]
Semantic evolution
The medieval senses are arming and equipping men, ships and crossbows, and in the Crónica Troiana knighting.[9] Morais (1789) lists armar cavaleiro “to knight”, with the ceremony of the order, and the figurative uses “to stir up” (a lawsuit, a quarrel), “to lay” (snares, traps) and armar às aves “to set snares for birds”; used intransitively it meant “to suit”, as in este traje não me arma “this dress does not suit me”.[11] Bluteau's book of synonyms gives “enlist soldiers” and “prepare to resist the enemy”.[12]
From making a weapon ready the verb passed to any device, structure or plan: setting a trap or a camera, putting up a tent or a hammock, plotting a scheme or causing a fuss.[2][1] Fabric that “arms well” hangs with body.[2] In Portugal armar-se em is to give oneself airs.[2][1] In Rio Grande do Sul it is also used for rolling a cigarette and preparing mate.[13]
